And you rub your hands together with the friction stick grasped in them, creating a friction point where the friction stick point is contacting a carved, hollowed receptacle spot in the log or large branch. This technique does not work quickly in wet conditions, obviously, but if your log/large branch receptacle is dry and your friction stick is dry, vigorous twirling between the hands will generate enough friction heat in the receptacle area to combust the dry shavings and kindling.
